Updated documentation
Updated samples
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Test for handles is updated according to behavior expected from modern compilers.
Performance test perf ncollection A1 is updated (valid range extended) according to measurements made on Debian 8 with GCC 4.9 and on Ubuntu 16.04 with CLang 3.8 and 6.0 and GCC 4.7, 4.9, and 5.0.
1. Extrema algorithm calls Curve-surface intersector. This intersector returns flag about infinite solution (in spite of extrema's returning not-parallel status correctly - axes of considered cylinder and circle are not parallel). In this case, attempt of obtaining number of intersection points leads to exception.
So, the fix adds check of infinite solution after the intersection algorithm.
2. The methods IsDone(), IsParallel(), NbExt(), SquareDistance() and Points() (of Extrema_* classes) have been corrected to make them consistent to the documentation.
3. Revision of some Extrema_* classes has been made in order to avoid places with uninitialized variables.
4. Currently Extrema does not store any points in case when the arguments are parallel. It stores the distance only.
5. Some cases on Extrema-algo have been moved from "fclasses"-group to "modalg"-group.
Function Strtod() is reimplemented using open source (MIT-style license) code by David M. Gay instead of strtod() provided by standard run-time library. This improves its performance by 3-10 times.
Functions Atof(), Strtod(), Printf(), Sprintf(), Fprintf() are declared as extern "C" to be usable from C programs.
Strtod() is used in Interface_FileReaderData::Fastof() and in RWStl_Reader to accelerate their work.
DRAW command QATestAtof and test perf fclasses strtod are added to check correctness and performance of Strtod().
Test perf draw restore is added to monitor performance of reading BREP files.
Minor off-topic corrections:
- method Standard_GUID::Assign (const Standard_UUID&) is implemented (was empty);
- Precision.hxx is included in BRepMesh_Vertex.hxx that uses it.
Tests are added to control output and performance of progress indicator (bugs fclasses bug28478 and perf fclasses progress, respectively).
Implementation of class Draw_ProgressIndicator is improved to update indicator basing on achieved total progress (1% by default) instead of elapsed time since last update.
Method OSD_Chronometer::Restart() is fixed to actually reset the counter.
DRAW command readstl is improved to show progress indicator if configured (by command XProgress).
Description of class Message_ProgressIndicator is updated; code example is added in description of Message_ProgressSentry.
Command checkplatform was created.
All test cases were updated.
Global variable os_type was eliminated.
New option -osx (MacOS) for procedure checkplatform was added.
Operator of cast to non-const reference is declared deprecated to produce compiler warning if used (usually implicitly).
OCCT code is updated to avoid that cast, occurring when function accepting non-const reference to handle is called with handle to derived type.
For that, local variable of argument type is passed instead, and down-cast is used to get it to desired type after the call.
A few occurrences of use of uninitialized variable are corrected.
A new script adm/upgrade.tcl defines a Tcl procedure occt_upgrade, to be used for upgrading code of OCCT and applications for changes introduced by OCCT 7.0.
Batch script upgrade.bat is provided for convenience.
File upgrade.dat contains data (lists of classes) required for some upgrade steps.
Details on upgrade procedure are put in dox/dev_guides/upgrade/upgrade.md.
OCCT code corrected to improve compatibility with code based on previous versions of OCCT:
- Added conversion operator of handle to bool, for use in conditional expressions.
- Forward declaration of argument class restored in macro DEFINE_STANDARD_HANDLE.
- Includes of used classes added in some headers to avoid problem of missing includes in dependent code
- Type cast operators to base curve and surface added in GC and GCE2d classes to reduce porting issues.
Added test for local reference to handle initialized by temporary handle to derived class.
WOK and CDL User Guides removed.
Debug code enabled with OCCT_DEBUG macro corrected for compiling with new handles.
QANCollection_Handle.cxx simplified so as to avoid need of using /bigobj option when building by Visual Studio; templates of project files, CMake projects, and test perf fclasses handle corrected accordingly.
Script genproj corrected to recognize VTK and to build DRAWEXE as executable (rather than DLL).
Test commands for checking performance and functionality of OCCT handles and RTTI added.
New test case added for that: test perf fclasses handle.
Implementation of opencascade::handle improved to enable compile-time error if two handles of incompatible types are compared.
Comparison of handle to NULL is not possible any more; method IsNull() should be used instead.
Method LDOM_MemManager::Doc() is removed to avoid cyclic dependency of headers; constructor of LDOM_Document(LDOM_MemManager&) is used directly instead.
Inclusion of headers corrected for compilation after previous patch.
Global static functions instantiating RTTI descriptors for class types (used though STANDARD_TYPE macro) are replaced by template static method Instance() of the class Standard_Type.
Implementation of RTTI is revised accordingly (global registry of type descriptors added to ensure single instance of each type descriptor shared by all dynamic libraries).
Obsolete methods of Standard_Type class (IsInstance(), Ancestors()) are removed; new method Parent() is added returning type descriptor of the parent class.
Class Standard_AncestorIterator is removed; this iteration can be easily done by recursive calls to Standard_Type::Parent().
Definition of macro STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_DefineHandle.hxx.
Inclusion of Standard_Type.hxx and the class header is now necessary for use of method DownCast() and function STANDARD_TYPE() for the class.
In general, Standard_Type.hxx should be included now instead of Standard_DefineHandle.hxx in places where these macros are used.
Macro DEFINE_STANDARD_EXCEPTION changed to define all methods inline; macro IMPLEMENT_STANDARD_EXCEPTION becomes obsolete.
Macros IMPLEMENT_DOWNCAST, IMPLEMENT_STANDARD_* become deprecated, they are still defined (as empty) for compatibility.
Implementation of Handle classes became fully inline.
Method get() is added in Handle classes returning pointer to the contained object.
RTTI removed from NCollection_Handle class.
Standard_Persistent is made empty descendant of Standard_Transient, instead of implementing its own hierarchy with reference counting.
Unused enumerations Standard_InternalType, Standard_WayOfLife, Standard_KindOfType are removed.
Global function HashCode() accepting Handle(Standard_Transient) is removed; HashCode() for Standard_CString with length should be used instead.
DRAW command dtryload is added for testing dynamic load / unload of the specified library.
New test perf fclasses bug24947 uses this command to measure performance of multiple (1000 times) loading / unloading OCCT libs on example of TKSTEP.
